2. Description of Related Art

Common object connection devices include connecting rings, shackles, pull rings, rope sockets, snatch blocks, hoist rings, swivels, swivel hoist rings, eye bolts, bearing swivels, hooks, buckles, connecting links, chains, ratchets, etc. The object connection devices are typically used to fix, lift, or tie goods or equipment, wherein each of the object connection devices has different models, sizes, mechanical properties, manufacturers, manufacturing dates, critical loads, service lives, maintenance processes, other related information, etc.

For safety, users must be familiar with the relevant information of each of the object connection devices. However, in practice, it is clearly difficult for users to bear the relevant information of various object connection devices in mind. In light of this, a load bearer with the contactless readable data carrier, which is similar to the aforementioned object connection devices, is disclosed in EP 2508461 B1, which allows the user to read the data stored on the data carrier to learn about the relevant information of the load bearer.

As shown in FIG. 21 in EP 2508461 B1, the data carrier 14 is fixed by generating friction between a load-receiving part 1 and retaining ribs 23. However, the retaining ribs 23 extends in a direction perpendicular to a surface 22, wherein such direction is parallel to the force that enables the data carrier 14 to be disengaged from the load-receiving part 1. In light of this, the way that the data carrier 14 in EP 2508461 B1 being fixed is not firm, so that the data carrier 14 may disengage from the load-receiving part 1. In all aspects, the conventional data carrier still has room for improvements.

BRIEF SUMMARY OF THE INVENTION

In view of the above, the primary objective of the present invention is to provide a contactless data carrier, which could be firmly fixed at an object connection device, and would not easily disengage therefrom.

The present invention provides a contactless data carrier, which is adapted to be disposed in a receiving portion of an object connection device, including a base and a tag member, wherein the base is adapted to be tucked into the receiving portion, and an outer peripheral surface of the base has a plurality of projections arranged at regular intervals. A top surface of each of the projections is adapted to abut against an inner surface of the receiving portion. The tag member is disposed at the base, wherein the tag member is stored with a piece of data relative to the object connection device. The tag member is adapted to be read in a contactless manner by a reading device.

With the aforementioned design, the outer peripheral surface of the base could firmly abut against the inner surface of the receiving portion of the object connection device, so that the contactless data carrier would not easily disengage therefrom.

DETAILED DESCRIPTION OF THE INVENTION

A contactless data carrier 100 of a first embodiment of the present invention and an object connection device which is a side-pull hoist ring 1 as an example are illustrated in FIG. 1, wherein the side-pull hoist ring 1 includes a bolt 1 a, an engaging member 1 b, and a bail 1 c. The engaging member 1 b is engaged with the bolt 1 a, and the bail 1 c is pivotally engaged with the engaging member 1 b, wherein a receiving portion, which is a blind hole 1 d as an example, is disposed on a side surface of the engaging member 1 b.

As shown in FIG. 2 and FIG. 3, the contactless data carrier 100 includes a base 10 and a tag member 20, wherein the base 10 is adapted to be tucked into the blind hole 1 d of the side-pull hoist ring 1, and has a top 10 a and a bottom 10 b opposite to the top 10 a. In practice, the base 10 is typically tucked into the blind hole 1 d with the bottom 10 b facing the blind hole 1 d. However, this is not a limitation of the present invention. In other embodiments, the base 10 could be tucked into the blind hole 1 d with the top 10 a facing the blind hole 1 d.

An outer peripheral surface of the base 10 has a plurality of projections 12 arranged at regular intervals, wherein a top surface 12 a of each of the projections 12 is adapted to abut against an inner surface of the blind hole 1 d.

In the current embodiment, the base 10 has four projections 12 as an example, wherein the projections 12 are arranged at regular intervals. However, the number of the projections is not a limitation of the present invention. In other embodiments, the base 10 could have three or more than four projections 12.

In the current embodiment, the base 10 is made of an elastic material, such as rubber, silicone, or other polymer materials. However, the material of the base is not a limitation of the present invention. In other embodiments, the base could be made of others elastomer, such as Thermoplastic Elastomer (TPE). Preferably, the base could be made of insulating materials. The advantage of using the elastic material is that when the base 10 is tucked into the blind hole 1 d, the projections 12 are pressed to be elastically deformed, so that the contact pressure between the projections 12 and the inner surface of the blind hole 1 d would be increased, especially the contact pressure in normal. Whereby, providing a tight performance, and the contactless data carrier 100 would not be easily disengaged. In addition, in the current embodiment, the top surface 12 a of each of the projections 12 is a convex surface, so that when the projections 12 is deformed, the top surface 12 a could abut against an inner surface of the receiving portion much closely, and the contactless data carrier 100 could be engaged with the blind hole 1 d tightly.

The tag member 20 is disposed at the base 10, and is stored with data of the side-pull hoist ring 1, such as models, mechanical properties, manufacturers, manufacturing date, critical load, service life, maintenance process, etc., wherein the stored data could be read in a contactless manner by a reading device (not shown) which is operable by a user. In an embodiment, the data stored in the tag member 20 could be a code, wherein the code is read by the reading device, and the corresponding data in a database could be retrieved according to the code, whereby to obtain the data of the corresponding object connection device.

In the current embodiment, the tag member 20 is a passive RFID (Radio Frequency Identification) electronic tag, and the reading device is an RFID reader, wherein the RFID reader is operable by the user to read the data stored in the RFID electronic tag. It is worth mentioning that, the data stored in the tag member 20 could be modified and stored again. For instance, the tag member 20 could be updated and stored with the data of the maintenance process again by the user when the side-pull hoist ring 1 is maintained or repaired.

However, the tag member 20 is not limited to be the passive RFID electronic tag, but could be semi-passive or active RFID electronic tags, or other equivalent structures, such as NFC electronic tags, ferrite NFC electronic tags, etc. In addition, in the current embodiment, the tag member 20 is disposed inside the base 10, which could prevent the tag member 20 from being polluted by foreign matters. However, the disposition of the tag member 20 is not a limitation of the present invention. In other embodiments, the tag member 20 could be disposed on an outer surface of the base 10.

As illustrated in FIG. 4, a contactless data carrier 200 of a second embodiment of the present invention has almost the same structure as that of the first embodiment, except that the outer peripheral surface of a base 210 has a plurality of annular grooves 214, wherein the annular grooves 214 respectively surround a plurality of projections 212. The annular grooves 214 could allow the projections 212 on the outer peripheral surface of the contactless data carrier 200 to be elastically deformed easily, whereby to abut against an inner surface of the receiving portion much closely.

As illustrated in FIG. 5, a contactless data carrier 300 of a third embodiment of the present invention has almost the same structure as that of the aforementioned embodiments, and is based on the first embodiment, except that a chamfer 313 is formed at a junction of an outer peripheral surface 311 of a base 310 and a bottom 312 of the base 310. In this way, the base 310 could be easily guided into the receiving portion when the contactless data carrier 300 is tucked into the receiving portion with the bottom 312 of the base 310 facing the receiving portion.
